When we conducted thousands of mock system design interviews on the Hello Interview platform, we often encountered candidates who had their interviews the next day or in a couple of days. The reality is that no one will become an expert in system design overnight. Therefore, we created the "System Design: Express Course": based on hundreds of real interviews, we identified the most common mistakes and compiled materials to help avoid them.
This course does not replace deep learning - it covers the most critical 20% that provide 80% of the effect. It is your brief, intensive, and practical path of preparation. We have focused only on what is actually tested in interviews and applied in real engineering practice.
